The countries that grow the most illegal Opium are Pakistan, Burma, Thailand, and Afghanistan, which is also the worldâs top supplier of Opium. Opium can also be grown in places like Mexico and Columbia. Afghanistan accounts to over 90% of the worldâs grown Opium.
This equation, I = V / R, tells us that the current, I, flowing through a circuit is directly proportional to the voltage, V, and inversely proportional to the resistance, R. In other words, if we increase the voltage, then the current will increase.
Since the current is the same throughout the circuit, knowing the current of a single component will give you the total current. Depending on whether you know the the total voltage or total power, use the equation Rt = Vt/It or Rt = Pt/It2 to calculate the total resistance. If you know total voltage and total current, you can use the equation Rt = Vt/It to calculate total resistance. 2  If you know the total power and the total voltage, you can use the equation Rt = Vt^2/Pt to calculate total resistance.
